I definitely will not click the “clean” button. This type of pop-up is usually malware or some kind of scam. So, when I encounter this pop-up, my immediate response is to close the browser. After that, I check if the system’s firewall is enabled, run the antivirus program to scan for any viruses or malware, update the browser to the latest version, and consider changing the password of the account that contains my personal information. By taking these preventive methods, I can ensure that my computer will be quite safe.
